I downloaded the video prior playing back. As I mentioned various programms
had severe issues playing back the local file. It lost AV-sync. I wasn't able
to skip forward, etc.
My system is an AMD E350 with 2x1.6GHz and normally perfectly able to play
back WebM stuff up to 1080p and H264 up to 720p without any hardware
acceleration. So it is rather unlikely that my system was cause of the
playback issues.
The transcoded version I grabbed from my Youtube upload didn't share any of
the issues mentioned above.
